Automobile vibration damping bumper

Abstract

The invention discloses an automobile vibration damping bumper, which comprises a bumper, a vibration damping mechanism, a buffer mechanism and a supporting mechanism. The two sides of the bumper main body of the bumper are sequentially provided with vibration damping rubber plates and auxiliary bumpers; the vibration damping mechanism It includes the first shock absorber, the second shock absorber, the guide rail frame and the buffer block. The two ends of the first shock absorber are respectively fixed on the auxiliary bumper and the buffer block by installing balls; the first buffer spring of the buffer mechanism, the connection The pad, the second buffer spring and the adjusting nut are sequentially connected and sleeved on the main body of the shock absorber, and the collision block is fixed at one end of the main body of the shock absorber; one end of the hydraulic cylinder of the supporting mechanism is hoisted in the guide tube through the fixed block, and the other end The supporting feet are connected by pin shafts. The arrangement of the bumper, the damping mechanism and the buffer mechanism of the present invention, when the vehicle collides from the front or oblique direction, multi-stage vibration damping, releases the supporting mechanism at the same time, increases the grip force and further improves the impact absorption performance of the bumper.

Description

technical field [0001] The invention relates to the field of shock absorbing devices, in particular to an automobile shock absorbing bumper. Background technique [0002] Cars are becoming more and more popular as a means of transportation with the improvement of people's living standards. Thereupon is the generation of traffic accident, and existing bumper is directly installed on the front and back end that is fixed on chassis, is the main contact position that car and car collide. [0003] A kind of safe and durable foam automobile bumper provided by Chinese Patent Publication No. CN206475844U, its core technology is to include a shell that is arranged sequentially from the outside to the inside, the first buffer reinforcement plate, the EPP foam material layer, the second The buffer reinforcement board, the foamed silica gel board, the vibration-damping rubber layer and the installation board, wherein, the first buffer reinforcement board has a base plate and grid-shape...

AI Technical Summary

Problems solved by technology

In the prior art, automobile bumpers are mostly made of a variety of materials with strong shock absorption performance and impact resistance, and at the same time, the overall structural strength of the bumper is enhanced, thereby reducing the degree of damage received when the automobile collides. However, due to the material limitations and the aesthetics of the vehicle do not produce a significant effect during a severe collision
